Description

  The present invention relates to a traction hook for use in traction of an automobile, and more particularly to an traction hook for an automobile that is most suitable for an automobile for racing.

  Tow hooks that are detachable from an automobile are known. This type of hook is assumed to be attached to an automobile during towing, and one end is a screwed portion to the vehicle body and the other end is a hook portion for hooking a tow rope or the like.

  Then, as a tow hook, a screw rod extending at the rear end of the hook portion is made to enter the inside of the vehicle body through a through hole provided in the bumper, and then one end is screwed to a mounting portion such as a reinforcement. Thus, a structure that is fixed to the vehicle body has been proposed (for example, Patent Documents 1 and 2).

  By the way, in the case of an automobile that runs for a race on a circuit or the like, it is required by the regulations to attach a tow hook in advance to the vehicle body in preparation for a situation where self-propulsion is impossible.

  In this case, when trying to run on a public road as it is, the hook portion of the above-described conventional towing hook protrudes out of the bumper, so it violates the safety standard, and the towing hook must be removed once. There was no trouble.

  Even when traveling on the circuit, there was a risk that the hook part protruding outside the bumper would pierce the opponent's car and cause great damage in the event of an unexpected contact accident.

  The tow hook for automobiles according to the present invention was created in view of the above-mentioned problems, and after one end enters the vehicle body through a through hole provided in the bumper, one end is attached to the attached portion inside the vehicle body. In the towing hook that is fixed to the vehicle body by screwing, an annular connecting member having a size that can penetrate the through hole provided in the bumper is provided at the other end of the towing hook body, and the annular connecting member is made of a non-rigid material. A flexible traction strap is inserted and fixed.

  According to a second aspect of the present invention, there is provided a tow hook for an automobile, wherein the tow hook is attached to the tow hook body with a screw rod extending from the rear end of the tow hook. It is characterized in that the amount of protrusion can be adjusted.

  The traction hook for automobiles of the present invention having the above-described configuration is such that the traction rope is connected to the traction hook via a flexible traction strap made of a non-rigid material, and the traction strap is provided at the other end of the traction hook body. It is fixed by inserting it into the formed annular connector. In this case, the annular connector is configured to be sized so as to be able to pass through the through hole provided in the bumper, so that the rigid portion of the tow hook is prevented from protruding from the bumper by retracting the annular connector into the vehicle body. Is done.

  Therefore, according to the present invention, there is no hindrance to running on public roads even with the tow hook attached, and it is possible to prevent damage to other vehicles even in the event of an unexpected contact accident on the circuit. .

  According to the second aspect of the present invention, the front-rear position of the annular coupler can be adjusted by advancing and retracting the annular coupler by rotating the screw rod, so that the distance between the mounted portion inside the vehicle body and the bumper depends on the vehicle type. Even in different cases, it is possible to cope with one type of tow hook.

The partially cut away side view of the disassembled state of the tow hook for automobiles of this invention. The side view of an assembly state as above. The top view of an assembly state same as the above. The front view of a tow hook main body same as the above. 1 is a partially cutaway side view of a tow hook for an automobile and an automobile in use according to the present invention. The side view of the tow hook for motor vehicles of this invention. The side view of the Example from which the traction hook main body of the traction hook for motor vehicles of this invention differs. The side view of the Example from which the traction hook main body of the traction hook for motor vehicles of this invention differs.

  Hereinafter, specific examples of the tow hook for automobiles of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a partially cutaway side view in an exploded state for showing each member of the tow hook according to the present invention. In the figure, reference numeral 1 denotes a metal pulling hook main body, one end of which is a male screw portion 2, which is screwed into a female screw portion R1 provided in a mounting portion R such as a reinforcement inside a vehicle body of an automobile. As a result, it is fixed to the vehicle body (see FIG. 5).

  In the figure, reference numeral 5 is a metal annular connector to which the traction strap 9 is fixed. In this embodiment, the annular connector 5 is not made to be the same body as the traction hook body 1 but is screwed into a female screw portion 4 provided in the traction hook body 1 with a screw rod 7 extending at the rear end. The tow hook body can be moved back and forth by the rotation of the rod (see FIG. 6). Reference numeral 3 in the figure is a polygonal portion provided on the peripheral side of the traction hook main body for fixing the traction hook main body 1 with a wrench or the like at the time of screwing, and reference numeral 8 in the figure is for fixing in the middle of the screwing. It is a fixing nut that is screwed into the screw rod 7 of the annular coupler 5.

  The annular connector 5 includes an annular body 6 through which the traction strap 9 is inserted, and the annular body is configured to have a size capable of penetrating through a through hole B1 provided in a bumper B of an automobile (see FIG. 5).

  In this embodiment, the flexible traction strap 9 made of a non-rigid material is made of cloth, and is folded back after one end 10 is inserted into the annular body 6 of the annular coupler 5, and the other end 12 is traction rope or the like (see FIG. (Not shown) are folded back in a loop shape so that they can be fixed, and each is overlapped and fixed by the sewing portion 11 (see FIGS. 2 and 3).

  The shape of the tow hook main body 1 is not limited to the illustrated one, and for example, the one shown in FIGS.
